Staff of worms but now paralyzes in area

Well, it's my first mod, my character is a witch and I had this skull staff, very cool, but VERY BUGGED, in the vanilla version the victims float and become invisible spirits and the body ends up in random places like hanging in the sky. But it's a beautiful staff, so I changed its enchantment to paralyze in area for 60 seconds. for instal is the same thing for all others put on data folder and add the plugin txt : staffofwormsparalized.rar
